Acceleration where velocity is changing

[tandoorichicken]

How would one describe the acceleration (linear and angular) if the velocity is constant but direction is constantly changing, i.e., circular motion?

 

[Fermat]

If the velocity (circumferential speed) is constant and motion is in a circle, then the acceleration is called centripetal acceleration.
Since the velocity is constant, then there is no linear (i.e. tangential) acceleration, or angular acceleration.

Is that what you were asking about?

 

[tandoorichicken]

Thanks fermat, so this means that both angular acceleration and the tangential acceleration = 0?

 

[Fermat]

If the peripheral velocity is constant,then that's right, yes.
